Who We Are
Washington Water Service (Washington Water) provides water utility services to 36,000 customer connections in about 200 Washington water systems from three regional offices and three field offices. The systems range in size from three to 15,000 service connections. As the largest investor-owned water utility in the state, we have the expertise and resources to tailor our services to meet the unique needs of each of our business partners.
Among our ranks are licensed electricians, general contractors, specialty plumbers, state-certified water distribution system operators, cross-connection control specialists, treatment plant operators, engineers, accountants, and customer service specialists. Every one of our employees participates in our Continuous Improvement program that identifies and implements projects that increase our efficiency or improve our customer service. We are regulated by the Washington Utilities and Transportation Commission, and have been designated by the state as a Satellite Management Agency in multiple counties throughout the state. And, we have received multiple awards from the Washington Department of Health for the service we provide to our customers. Our customers rely on us to provide a reliable supply of high-quality water, timely emergency services, personal response to their calls, convenient payment options, and an information-packed web site.
In 2020, we acquired Rainier View Water Company, which was adjacent to our East Gig Harbor operations. We look forward to providing the same quality, service, and value to our new customers as we are committed to delivering to our existing customers.
What We Do and Who We Serve
We provide a range of professional water utility services, including customer service, meter reading, water quality monitoring, water system maintenance and operations, engineering, construction, and assistance with rate filings to homeowner associations, municipalities, special districts, mutual water companies, and other water system owners.
What Our Organization Looks Like
We provide customer service from our Customer Center in Gig Harbor and East Pierce County. We provide operations to our northwest region customers from the Gig Harbor location and our three field offices in Sequim, Issaquah, and Orcas Island. Operations for our southwest region customers are provided from our regional office in Olympia. Washington Water is a subsidiary of California Water Service Group, a water utility company traded on the New York Stock Exchange under the symbol “CWT.” Other company subsidiaries include California Water Service, New Mexico Water Service, Texas Water Service, and Hawaii Water Service. Being part of a larger organization gives Washington Water access to resources and expertise that a smaller, local company may not have.
What We Can Do For Water Systems
Whether you are finding it a challenge to meet increasingly stringent water quality standards, respond to after-hours water system emergencies, or make necessary upgrades to your water system, Washington Water can help. Do you need someone to answer customer calls around the clock? Someone to respond quickly to customer emergencies in the middle of the night? Someone to design and invest in upgrades to your water system? Someone to perform maintenance and repairs? Someone to purchase your system and assume all operational responsibilities? Whatever your needs, we can offer a hassle-free, cost-competitive solution.
How We Started: A Marriage of Water System Engineering and Construction
Washington Water Service traces its roots back over 35 years through South Sound Utilities and Harbor Water Company Inc., two firms that worked together as early as 1975 to design and construct water systems in Washington. Washington Water was formed in 1999 with the purchase of Harbor Water Company in Gig Harbor and South Sound Utilities in Olympia. And just six months later, Washington Water acquired the assets and employees of Robischon Engineers to form an in-house Engineering Department. Today, Washington Water employs more than 50 Washington-based employees, several of whom have over 30 years of experience in the water utility industry.
